I turned 33 today, weigh 62 kgs (slender), 1,72 height, dont drink, smoke or eat unhealthy but have been diagnosed with anxiety...i dont get panic attacks anymore but when I get these skipped heart beats it sort of triggers me to be on edge. i have had skipped/flip flop sensations in my chest that have made me anxious for the past 3years....I could go without them for 2months but this last week it has been happening at least twice a day - could it be because I have gone back to exercising(aerobics)? Most information on websites says if they are frequesnt you need to see a doc but how many times is really frequent?? Is it when it happens every hour or every 30 min or is it when the episode lasts more than a minute?
